Comments "...mechanical studies of cells treated with the drug latrunculin (which depolymerizes the majority of actin polymers) indicate that ~90% of the cortical mechanical properties are contributed by the actin network (primary sources) Therefore, the membrane contributes only a small fraction to these parameters (cortical viscoelasticity and tension)."
